$8.(10$p$)($Adding Salt$\backslash$&Pepper Noise to the Image$)$ Write your own Matlab code to add $1$d$\backslash \%($if the last digit of your ID is $7,$ then $17\backslash \%,$ i$.$e$.$ the probability of a pixel to be noisy should be $0\mathrm{.}17)$ salt$\backslash$&pepper noise to your images. Do not use "imnoise" function. Repeat it by adding $2$d$\backslash \%$ salt$\backslash$&pepper noise. Display and report the resultant images side by side in the same figure. Draw the histograms of the original and the noisy yourName $\_$gray images side by side in anotner migure. Comment on the results briefly.
